SPINDLE FOR YARN-WINDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 348,560, dated September 7, 1886.

Application filed May 8, i886. Serial No. 201,519. (No model.)

To all 1077,0771/ it may concer-72,:

Beit known that I, WARREN D. HUsE, of Laconia, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements in Spindles for YarnVinding l\'lachin'es, of which the following, taken in connection with the accompanying drawings, is a speciiication.

My invention relates to spindles for yarnwinding machines and the means of operating them, audit consists in certain novel features of construction, arrangement, and combination of parts,which will be readily understood by reference to the description of the drawings, and to the claims to be hereinafter given.

Figure l of the drawings is a vertical transverse section through the spindle-rails of a winding-machine, and showing one of my improved spindles and its shipping mechanism in elevation with a bobbin mounted upon said spindle. Fig. 2 is a front elevation of said spindle, the shipping mechanism,and portions of the supporting-rails with the bobbin removed; and Fig. 3 is a vertical section on line x x on Fig. 2, except that the spindle and set. screws are shown in elevation.

In the drawings, A and A are the spindlesupporting rails of a yarn-winding machine, which are maintained in their proper relative positions by the end frames (not shown) of the machine in a well-known manner.

Bis an oil-cup set in axed position in the rail A, and provided with an upwardly-projecting central hub, a, in the periphery of which is formed the spiral groove a', extending from the upper end to near the lower end of said hub, where it communicates by means of the hole a2 with the interior of the cylindrical chamber formed in the center of said hub, and in which the lower end of the spindle C has its bearing.

D is a grooved pulley, provided with the downward]y-projecting hub d, and mounted upon the hub a of the oil-cup B,with thelower end of its hub d resting upon the bottom of said oil-cup, said pulley being arranged to revolve freely upon the hub a without any contact whatever with the spindle C. The upper end of the pulley D is a fiat circular plane at right angles to its axis of revolution, and arranged to engaged with a corresponding face on the under surface of the disk E, which is provided with the hub e, havin(r upon its upper end the collar or flange c, and secured iirmly to the spindle O by means of the setscrew c, or in any other well-known manner. The spindle Chas its upper bearing in the bushing F, set in the rail A, and has firmly secured thereon, above said upper bearing, the disk G, upon which the bobbin H rests when placed upon the spindle O.

I is a bracket or stand secured to the lower spindle-rail, A, and having pivoted4 thereon the shipper-lever J by means of the inclined pivot bolt f, about the axis of which said lever may be vibrated a distancelimited by the earsg and g on the front end of the bracket I, as shown in Fig. 2. The inner end of the lever J extends under the collar e'on the hub of the disk E, so that when the front or outer end of 'the lever J is moved to the left about its inclined fulcrum-pin f its inner end will engage with said collar and lift the disk E away from contact with the pulley D,carrying with it the spindle C and the bobbin H, as shown in Figs. l and 2.

The operation of my invention is as follows: The parts beingin the positions shown in Figs. 1 and 2, and the bobbin being placed upon the spindle, and the yarn being properly connected to said bobbin, the front or outer end of the lever J is moved to the right about its fulcrum-boltf,when the bobbin, the spindle,and the disk E all move downward until the lower surface of the said disk comes in contact with the upper surface ofthe pulley, when said disk, spindle, and bobbin will be revolved by virtue of the friction between the contiguous surfaces of said disk and pulley, caused by the force of gravity or the weight of the parts. The

commencement of the revolution of the spindle is very easy and gradual, and therefore is much less liable to break the yarn in starting than when the old-fashioned clutchisused. Then it becomes desirable to stop the revolution of the bobbin,the frontend of theleverJ is moved to the left to lift the disk E from contact with the pulley D, as before described. A spring, h, is interposed between the head of the fulcrum-bolt j and the lever J, by compressing which the lever J may be raised over the ears g or g and swung at right angles to its normal position whenever it is desired to remove the spindle. The front end of the bracket I has formed thereon intermediate between the ears g and g the raised nib i, which serves to retain the lever J in either position in which it may be placed between the ears g and g.

The lever J may be mounted upon a horizontal pin and move in a vertical plane, instead of an inclined plane, as shown, if desired,without departing from the principles of my invention7 though I prefer the arrangement shown.

NVhat I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination of the spindle O,tl1e disk E, Iirml y secured to said spindle and provided With the hub e and collar e', the loose pulley D, a fixed bearing for said pulley, the bracket I, provided with the ears g and g' and the nib i', the level` J, and theinclined fulcrum-pinf, all constructed, arranged, and adapted'to operate substantially as and for the purposes described.

2. In combination with the vertically-mov able spindle C, the disk E, provided with the collar c', and the lever J, for raising the same, the bracket I, provided with the ears g g and the nib i, the fulerum-b0ltf,tl1c spring ininter- Witnesses:
